Abstract: Изобретение относится к пылесосу с низким уровнем создаваемого им шума. Пылесос содержит корпус, внутри которого расположены сборник загрязнений, вентиляторный электродвигатель и выпускной канал, проточно сообщающийся с вентиляторным электродвигателем. Поперечное сечение выпускного канала имеет прямоугольную форму и его длинная сторона более чем в два раза превышает его короткую сторону. В одном конце выпускного канала в направлении, перпендикулярном направлению протекания воздуха внутри выпускного канала, образован выход. В выпускном канале в направлении протекания воздуха расположен звукопоглощающий элемент, толщина которого меньше, чем длина короткой стороны сечения выпускного канала. Часть воздуха, выпущенного из вентиляторного электродвигателя, протекает через внутреннее пространство выпускного канала, в котором отсутствует звукопоглощающий элемент, а часть воздуха протекает через звукопоглощающий элемент, после чего воздух выпускается наружу корпуса пылесоса через выход выпускного канала. Внутри корпуса пылесоса расположен кожух сборника загрязнений, огораживающий сборник загрязнений. С кожухом сборника загрязнений соединен кожух двигателя, обеспечивающий протекание выпускаемого из вентиляторного электродвигателя воздуха по направлению к нижней поверхности корпуса пылесоса. Выпускной канал образован обеими боковыми поверхностями кожуха сборника загрязнений и обеими боковыми поверхностями корпуса пылесоса. Технический результат состоит в снижении уровня шума, создаваемого при выбросе воздуха, за счет плавного выпуска воздуха наружу из пылесоса. 11 з.п. ф-лы, 9 ил.
